带有矩形孔阵列的Au-介质-Au多层膜的透射特性

摘要
周期性亚波长孔阵列的异常透射性质在亚波长光电器件设计中具有重要意义。两层或更多膜层上周期孔阵列结构,由于层之间电磁场的相互作用可以导致新的光学性质。利用时域有限差分方法理论研究了带有矩形孔阵列的Au-介质-Au多层膜的透射特性。结果表明:该结构在近红外波段的透射谱存在多个透射峰,并且透射峰的数量、位置和强度可以通过改变结构的几何参数和介质膜的材料进行调控。详细分析了介质膜的厚度和折射率、孔阵列的周期、矩形孔的边长等因素对多层膜矩形孔阵列透射谱的影响,为利用多个表面等离子共振设计多波长控制器件提供了一定的参考。
The extraordinary optical transmission properties of periodic subwavelength hole arrays were of great significance in the design of subwavelength optoelectronic devices. The periodic hole array structure on two or more layers can lead to new optical properties due to the interaction of the electromagnetic fields between the layers. The transmission properties of a rectangular nanohole array in Au-dielectric-Au multilayer films were simulated using the finite-difference time-domain method. The results show that there are multiple transmission peaks in the transmission spectra of the structure in the near-infrared region.The number, position and intensity of the transmission peak can be controlled by changing the geometrical parameters of the structure and the dielectric film of material. The influences of the thickness and refractive index of the dielectric film, the period of the hole arrays, the length of the rectangular hole on the transmission spectrum were analyzed in detail. It provides a reference for designing multi-wavelength control devices using multiple surface plasmon resonances.
